IMPROVEMENT IN CARD-CLOTHING- CLAMPS The Schedule: referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that I, J osnUA O..Lnw1s, of the city and county of Worcester, and Commonwealth of Massachusetts, have invented certain new and useful Imrovements in Card-ClothingClamps; and I do hereby (eclare that the following is afull, clear, and exact description of.th e same, reference being had to the accompanying drawings, forming a part of this specilication, in whichl Figure 1 represents a perspective view of my improved clamp; 4, I

Figure 2 represents a cross-section through the jaws; and

Figure 3 represents a cross-section through the jaws of theclamp, as made prior to"my present improvement.

i To enable those skilled in 'the art to which my invention belongs, to make and use'the same, I will proceed to describe it more in detail.

The nature of my invention relates to an improvement upon the card-clotliing clamp for which Letters' Patent were granted to me April 11, 1865, and consists in the peculiar form and construction of the lips of the jaws, as willhe hereafter explained.

In the drawiugs- A is the upper, and B, the lower jaw. i

The rear operating levers C and Dare constructed and operated the same as in my patent above referred to, but the lips a and l) are constructed differently.

. The front edge ofthe lip b of the under jaw is bevelled back from l'to 2, and the upper side of the .same jaw is bevelled oil' from 2 to 3, while the front edge of the upper jaw is bevelled under from 4 to 5, and then bevelled up and back from 5 to 6, as fully indicated in,` g. 2 of the drawings.

By making the lips Vof the jaws in themanner as shown and described, the grasp upon the edge of the card clothing is more secure and iirln, while, at' the same time, there .is not that liabilityY of cutting the leather during the ope-ration of clothing the cards, as there is in the use of the clamp as used prior to my present invention, the lips of which are inade in the l form as shown in tlg. 3, and by reference to which it will be seen that the leather is clamped between the points 7 and 8, and that when the jaws are forced t0- gether suliiciently tight to hold the cardclot-hin g while `it is'being drawn or secured in position, the sharp proved clamp, as showuin figs. 1 and 2 in the accompanying drawings.

Having described my improvementsliu card clothing What I claim therein as new and of my invention, and desire to secure by Letters Patent, as an improve ment upon the Vclamp patented to me April l, 1865, s-

The combination of the jaws A B, having lips a b,

Y made with bevelled surfaces 1, 2, 3, and 4, 5, 6, as and -forthe purposes shown and described.'
